Update, I realized I could use less voltage for 4ghz after 4.2ghz tested stable on air (in super low ambients, super low ambients for this new result also): 21x190 3.99ghz, turbo on, HT on, 1.3125v load, 1.328v idle, 1.315 VTT, 3420mhz QPI, 3040mhz Uncore, 1520mhz memory @ 8-8-8-21-2T with...

Use CPU-Z to verify your actual Uncore and QPI speeds. By far the easiest way to hit 3.8ghz is to use 21x181 by enabling turbo. If your RAM isn't able to do 1448mhz (181 bclk @ 8x mem multi) you will have to set the memory multi to 6x for 1086mhz and set the Uncore multi to 12x which is the...

This is the farthest I'm willing to push the chip on air, and even then just to see what it can do in case I want to improve my cooling setup: i7-920, 3841A383 from Newegg: 21 x 200 4.2ghz, turbo on, HT on, 1.408v load, 1.424v idle, 1.395v VTT, 3200mhz Uncore, 1600mhz memory @ 9-9-9-24-2T...

Yes, we are using up to 2.0v in some cases. The highest I have gone so far was 1.8 trying to get 3600mhz Uncore stable with 4.2ghz with HT running 8 thread software. The key is to keep QPI/VTT within 0.5 volts -max- from the DRAM voltage. The max recommended value for QPI/VTT is 1.35v by...

A quick tip if you are having trouble with overclocking stability with 3 x 2gig sticks on your Core i7 system: ditch 1T command rate. I'm not losing performance from it, just gaining instability with it at high BCLKs with 3 modules. It's fine for 2 modules for my system however. I started...

I haven't seen any data to indicate that yet. I am diligently raising VTT one step at a time until it's stable with 6 gig triple channel in Prime blend. I needed 1.275v VTT for 4 gigs dual channel and with all the same settings except the added third memory stick I am now up to 1.395v VTT and...

Did you lower your Uncore multiplier? Also you need to raise QPI (VTT) voltage as you stress the memory more. I just had to go from 1.275v to 1.375v VTT to get stability back when I went from dual channel to triple channel at 3.8ghz with HT. At 4.0ghz with HT I already needed 1.375v VTT with...

It will go into the 80s for LinX (or similar torture test) if you use all the memory you can get away with. I seem to be getting similar temps to you with my TRUE-120 2100rpm push-pull but I have my board mounted to the removable tray from my case laying flat on a table with ceiling fan...

Yep, I don't believe you. Get RealTemp version 2.90, it reads higher than 2.70.

I'm assuming you have HT enabled because you are unstable at 1.35 vCore. Try lowering CPU PLL back to default. What was your reason to raise it? I don't think there's any conclusive evidence it's helpful on the i7 platform yet (at 20x200). Also increase your vCore to at least 1.375v in the...

Very impressive. Your DFI board seems to have more useful settings for voltage than my Gigabyte. :( I am unable to boost at 210 BCLK no matter what the multi or Uncore/Memory speeds or timings. I am very stable at every variation of 200 BCLK however. Is it true that to go much past 200...

I think I've seen people get 19x211 stable on the Gigabyte boards but I don't know how they did it. I've been stable at 20x200 since BIOS F5a. I've used 19x191 with turbo which is another interesting option and stable but I'd like to dial in 19x211 with no turbo if I can!

When you first tried 20x200 @ 1.40000v bios did you have your vQPI up to 1.355 already? Try 1.375v QPI with 20x200 if you haven't yet.

Try lowering your UCLK to 200 and using turbo to reach 4.2ghz instead. This will relieve the stress on the memory system and should allow lower volts (on QPI for sure, should also get a few steps on vCore) so you can get the temps down a bit. I am also able to run with 8-8-8-21-1T since I'm...

I agree, maybe I should have said I agreed with a ~1.35-1.45v limit depending on cooling for 24/7 reliability. I am using 1.264 load (1.30 BIOS) for 4ghz no HT (sigh, up from 1.244 which was stable with colder ambients). With HT I'm using 1.360 load (1.40625 BIOS). I wonder if the ~0.1 volt...

The actual maximum voltage set by intel is 1.55v. Here is a link to a reference: http://www.xtremesystems.org/forums/showpost.php?p=3492869&postcount=845

I've had great results with the A-batch chip I bought from Newegg: http://www.hardforum.com/showpost.php?p=1033562115&postcount=274

Excellent result Rossi! I must do testing with 19x multi! I have done some initial testing with 20x multi for 4ghz: Vista Ultimate SP1 64-bit Gigabyte GA-EX58-UD5 @ F5d G.Skill F3-12800C8-2GBPI-B x 2 @ 1600mhz 2:8, 8-8-8-21-1T Ci7-920 (3841A383 from Newegg) TRUE 120 Extreme with...

Well I fretted about it last night and finally decided to keep the monitor. I had until yesterday to return it due to the holiday shopping courtesy of Best Buy to greatly increase their allowable return time. I must say there are only two gripes I have about this monitor after all this time...

I just did a reset in the monitor's OSD and used EZTune to do the calibration. I may not have a good eye for matching the color of that box so that it blends in on each step because the result was not very good. Using the following calibration website for comparison the first two boxes looked...

I haven't done any testing like that yet as far as the input lag. However my initial impression of gaming on this monitor is: "What input lag?". I'm pretty sure you'll have to get a DVI to HDMI adapter to view the full quality image from a Blu-ray or HD-DVD player. I definitely think you'll...

When I set 1920x1080 in the display control panel with 1:1 set in the monitor's menu I get a nice non-stretched image with black bars on the top and bottom. I'm not sure if I forgot to mention it but I am using DVI to connect to my PC. I can try the VGA connection to my PC tonight but I doubt...

Bad news: no 1080p over component. When I attempted to enable 1080p in the XBox 360 over component input 1 I got a distorted green 480p image. When I attempted the same on component input 2 I got a 480p image that looked pretty much fine. For both component inputs the monitor's OSD had no...

Wow, I've really been living under a rock playing too much World of Warcraft. I've been reading about the recently added 1080p support for XBox 360 online just now. I'm going to head home for lunch and test it out real quick for you guys. -JWM

Forgive me as I am a noob with the XBox 360 1080p thing. I'm at work right now so I can't check: is 1080p enabled in the system settings on the 360? I hooked the 360 up via component, fired up Gears of War, and the monitor's menu said the resolution was 1080i. I felt the image quality was...

Well, I just bought one from the local Best Buy. I went over there on the second day of our state's no sales tax shopping spree to see what they had left and there it was. There were no specimens up for display but the good price point, no tax and good feature set were too enticing to pass up...

I finally updated my post with the week and code information for my E6600. I bought an L630A E6600 from TankGuys to go for some better overclocking but I'm not ready to post any results yet. My original E6600 which I posted the 3.4ghz overclock results for is an L625A. The reason I didn't...

So far it seems that my E6600 L630A isn't all that great. I have the P5W DH and with 1.35 vCore set in BIOS and 400 x 9 I get a spontaneous reboot when windows tries to start booting. However, with increased voltage I have achieved 3 hour Orthos large-fft stability (I stopped the stress...

I noticed this same problem myself and I have an ATI video card. I'm seeing a trend here of people saying this never happens to them who all have nVidia video cards. I have 2GB ram for one so heavy paging is a non issue for me. I'm also pretty sure I've seen this even after turning my page...

Lol... I updated it again: http://www.hardforum.com/showpost.php?p=1029880808&postcount=364 I added the CPU-z validation link. Also I had previously added the BIOS version too (P5W DH, version 1101). Will I remain unofficial until I can get the week and code values of my CPU? It...

I just started using Orthos because I heard it was the most stressful thing you can do to your cpu/ram/mch. I've been searching for the highest 100% guaranteed no issues whatsoever overclock that I could acheive. It looks like 3.4 is it for this level of stability with my chip on air cooling...

I can do 3.6 too.. but Orthos explodes almost instantly... You're braver than I am. -JWM

Thanks for providing all your settings vanilla_guerilla. I was already able to boot at 400 x 9 with 1.500 vCore but Orthos large fft failed within seconds. I increased the vCore in steps and stopped at 1.5750 when it continued to bomb out in like 5 seconds. I tried all of your settings in...

I am using BIOS 1101 and manual timings of 4-4-4-12. I had slight instability at that voltage setting and 380x9 so I upped it to 1.500. Yea, I've read that the max bootable overclock and mem timings is a good bit less than what you can get with setting memory timings and bus speeds with...

But what setting did you use in the BIOS? I know this board has some voltage droop and CPU-Z reads it wrong at bios settings of 1.500 and up. The largest vCore I've set so far is 1.500 and that got me stable at 378 x 9 with all other voltages stock and ram @ 4-4-4-12 and 1:1. I bet I could...

I edited my earlier post to show proof of the overclock and I also backed the FSB off 2mhz so I went down in speed slightly. Edit: My bad, here's the link to my earlier post: http://www.hardforum.com/showpost.php?p=1029880808&postcount=364 -JWM

Are you also stable using 'Large, in-place FFTs - stress som RAM' ? This is the only test I have been using so far and I am unable to get stability with a vCore setting of anything less than 1.500 in the BIOS. My system: E6600 OEM Stepping 6 B2 Week: L625 Code: A404 P5W DH Deluxe with...

Ditto. It still says in stock too so those of you in a hurry to get one should hop to it. :) -JWM

I know the mobo prices are getting a bit nuts now. But serious server motherboards have been far more expensive for a while now. The dual xeon mobo in our supermicro 2U rackmount server cost almost $600 and a Tyan Thunder K8W dual opteron is about $400. -JWM

Yea I think what he meant was that Conroe will respond very well to extreme cooling when overclocking. Sure enough, it does and the performance scales incredibly well: X6800 @ 5.4ghz on liquid nitrogen: http://www.xtremesystems.org/forums/showthread.php?t=107758 E6700 @ 4.6ghz on single...
